Re: Wyeast 1469 lag?

… As I understand it, dried yeast comes with all componds needed for growth but stepped up yeast have to manufacture these compounds and Oxygen is needed to do this. That's right. As I understand it those compounds are what is needed to create more cells (cell membranes). And those compounds (stero...

Re: Wyeast 1469 lag?

I'm planning to use 1469 yeast later this year. It'll only be the second time I've used it. The first time … … Big fan of 1469 yeast. It's relatively lively so fit a blow off if your fermenter is full. … in several years of using liquid yeast, 1469 is the only yeast I've had to fit a "blow off" tube...

You started it! Trying to confound me with "negative pressure" 'stead of "suck" :P

Re: How to improve mash tun flow through

If the lack of seal means fluid can go around the impeller blades faster than it can be pushed along, then liquid isn't being displaced. So there is no "negative pressure". The blades just go round and round, and if any air is getting in, mixing up a fine froth. The blades can be made to fit closer,...

Re: How to improve mash tun flow through

Despite what I said above, people still use the suc... word. These impeller pumps cannot suck! However, the weight of wort above the pump can push the wort through the pump which will have the same effect (debris/grain compaction, etc.). There are pumps that will suck, they'll also most probably be ...

Re: Floating dip tube for corny

I've never had any issues with the 6.5mm silicone hose coming off a gas dip tube without the need for any clamp. I do recommend removing it between brews and giving it a proper clean (or boil) to remove any bio film though. I'll have to look at that 6.5mm bore stuff (or 6mm bore will do). I know yo...

Re: Alkalinity and Salifert kit

… I think HCO3 is what is known as bicarbonate, but I admit I get a little confused about the differences between alkalinity as CACO3 and HCO3 and what the salifert kit is telling me. … There is virtually no carbonate, or in many cases no carbonate, in UK tap water; it will all be bicarbonate.

Re: How to improve mash tun flow through

Should do the job! I do know people will use the tiny 12V "solar" style pumps: They foul up with debris as soon as look at them. Could be pumping too fast? As Jocky has already said. Seems wrong (debris clogging the pipes might be more intuitive reasoning) but those pumps can only push the wort alon...

Re: How to improve mash tun flow through

What pump? I can't see what you're doing that is much different to what I'm doing. But you haven't described what pump you use.

Re: Floating dip tube for corny

As usual, I take forever to create follow ups for these threads. This is a sample of a few of my floating dip-tubes using "Cask Widge" parts: 20200829_190837__WEB.jpg I purchase the Cask Widge floating extractors on their own and get a length of silicon "milk hose" (eBay) separately to have the righ...

Re: Hop filter

If the geometry of the filter is a bit baffling in the photo above, this is one with the filter in-situ: 20200831_185856_WEB.jpg It wasn't my intention to include the old gauze "snorkel", but the filter was cut a bit short and the snorkel fills the space. With hindsight the snorkel relieves the filt...

Re: Chinese 8mm threads (temperature probe)

I'm sure they are. There will be some leeway. Just as long as others reading this don't think there isn't an issue (they may not be so lucky).

Just like me suggesting you can screw male NPT (1/2" & 3/4") into female BSPP. It'll most likely work, but that doesn't make it right.

… Then there are the 5/16" (7.94mm) options, UNC/BSW at 18TPI, BSF at 22TPI, and UNF at 24TPI … Damn, missed British Standard Fine (BSF).
